Harvesting UV Photons for Solar Energy Conversion Applications

Jacques-Edouard Moser, Magdalena Anna Marszalek

We report the synthesis and characterization of five new donor–π–spacer–acceptor dye molecules with a diphenylamine donor, fluorene–1,2,5-oxadiazole spacers and a range of acceptor/anchor groups (carboxylic acid 1, cyanoacrylic acid 2 and 3, alcohol 4 and ...

The influence of microstructure on charge separation dynamics in organic bulk heterojunction materials for solar cell applications

Jacques-Edouard Moser, Natalie Renuka Banerji, Arun Aby Paraecattil, Mariateresa Scarongella, Natalie Stingelin

Light-induced charge formation is essential for the generation of photocurrent in organic solar cells. In order to gain a better understanding of this complex process, we have investigated the femtosecond dynamics of charge separation upon selective excita ...

Time-independent, high electron mobility in thin PC61BM films: Relevance to organic photovoltaics

Jacques-Edouard Moser

Ultrafast optical probing of electric field by means of electroabsorption combined with conventional photocurrent measurements was employed to investigate the drift and mobility dynamics of photo-generated charge carriers in the pristine PC61BM film and in ...

New pyrido[3,4-b]pyrazine-based sensitizers for efficient and stable dye-sensitized solar cells

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Pascal Comte, Thomas Moehl, Mateusz Barnaba Wielopolski, Jiabao Yang

A series of new pyrido[3,4-b]pyrazine-based organic sensitizers (PP-I and APP-I–IV) containing different donors and p-spacers have been synthesized and employed in dye-sensitized solar cells (DSSCs). The absorption spectra properties of dyes are analysed b ...

Unravelling the mechanism of photoinduced charge transfer processes in lead iodide perovskite solar cells

Jacques-Edouard Moser, Arianna Marchioro, Thomas Moehl, Joël Teuscher

Lead halide perovskites have recently been used as light absorbers in hybrid organic–inorganic solid-state solar cells, with efficiencies as high as 15% and open-circuit voltages of 1 V. However, a detailed explanation of the mechanisms of operation within ...

Kinetics of the Regeneration by Iodide of Dye Sensitizers Adsorbed on Mesoporous Titania

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Arianna Marchioro, Julien Alexandre Andres, Peng Wang, Joël Teuscher

Regeneration of dye sensitizer molecules by reducing species contained in the electrolyte is a key mechanism in liquid dye-sensitized solar cells because it competes kinetically with a detrimental charge recombination process. Kinetics of the reduction by ...

A New Anti-Counterfeiting Feature Relying on Invisible Luminescent Full Color Images Printed with Lanthanide-Based Inks

Roger Hersch, Jacques-Edouard Moser, Anne-Sophie Chauvin, Julien Alexandre Andres

Europium and terbium trisdipicolinate complexes are inkjet printed onto paper with commercially available desktop inkjet printers. Together with a commercial blue luminescent ink, the red-emitting luminescent ink containing europium and the green-emitting ...

Position-Dependent Extension of π-Conjugation in D-π-A Dye Sensitizers and the Impact on the Charge-Transfer Properties

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Jinhyun Kim, Thomas Wesley Holcombe, Mateusz Barnaba Wielopolski, Yuxiang Yu

A series of five organic donor-π-bridge-acceptor (D-π-A) sensitizers is investigated within the context of their photoinduced charge-transfer properties. Thereby, the focus is set on the impact of structural modifications of the molecular architecture on t ...

Molecular Engineering of a Fluorene Donor for Dye-Sensitized Solar Cells

Mohammad Khaja Nazeeruddin, Ursula Röthlisberger, Jacques-Edouard Moser, Ivano Tavernelli, Robin Humphry-Baker, Joël Teuscher, Basile Curchod, Aswani Yella, Negar Ashari Astani, Julien Edouard Frey, Simon Mathew, Lauren Elizabeth Polander

To improve their efficiency beyond the state-of-the-art, D-pi-A dyes must display increased spectral breadth and account for the physical limitations observed in the dye. sensitized solar cells. In particular, they should be designed to control the electro ...
